Topology detection in an electric power distribution grid

A computing device, comprising:

• at least one processor;
• and
• at least one memory device having processor-executable instructions stored thereon that, in response to execution by the at least one processor, cause the computing device to:
• access phasor data associated with an electric power circuit including an arrangement of switching devices and multiple phasor measurement units;
• determine, based on historical phasor data, a maximum value of current amplitude on the switching devices in an open state and a minimum value of current amplitude on the switching devices in a closed state;
• determine, based on the maximum value of current amplitude and the minimum value of current amplitude, individualized zero-current thresholds for the multiple phasor measurement units;
• determine one or more zero-current branches present in the arrangement of switching devices by applying the individualized zero-current thresholds to the phasor data;
• and
• determine, based on the one or more zero-current branches, a circuit topology by selectively opening and closing the arrangement of switching devices.

• determine, based on the maximum value of current amplitude and the minimum value of current amplitude, individualized zero-current thresholds for the multiple phasor measurement units;
• determine one or more zero-current branches present in the arrangement of switching devices by applying the individualized zero-current thresholds to the phasor data;
• and
• determine, based on the one or more zero-current branches, a circuit topology by selectively opening and closing the arrangement of switching devices.
